Breadboarding RAM - Hack a Day

If you’ve ever wanted to dive in and take a look at how memory hardware is implemented here is a good example of how to implement some latching circuits with ether BJT or CMOS transistors. BJTs require biasing resistors which increases the complexity and power consumption when compared to CMOS. If power consumption isn’t an issue you could certainly make some really fast logic.

Most modern on chip RAM is made using SRAM because it only takes six transistors to implement(vs eight) and is pretty fast. When it comes to density DRAM can get one bit of storage by using a single transistor and capacitor(putting the capacitor underneath he transistor can save even more space). All that said, latches and flip flops are still a very useful (and common) tool when working with digital circuits.

About Me

Hi I'm Don,
I write, sing and record songs of my own and I like doing this very much. My music is on my web site. My first album is called DonSongs and my second one is called Living Beings - Climate Control. You can Download and listen and save all our songs on my web site at DonSongs.com and it's completely free. My favorite hobby now is computers. I like to fix old Computers and make them usable again with different Linux Operating Systems or just fix up messed up WindBlows systems;). I really like researching interesting things on the Internet. I read allot about many things, Technical things on computers and the Internet, interesting discoveries in science, new technology, local and world news and just what ever strikes me as interesting. I am very handy and good with tools, fixing and making things. I like to help my friends with their projects when I can. I love Hot Rods and use to do Motor Swaps and put Big Block Chevy Motors where 6 cylinders once were. I love 4 Wheeling and Dirt Bike Riding But I don't have a motorcycle any more. I still really like 4 Wheeling in my 1976 Chevy Blazer, when I can afford the Gas and cost of Broken Parts that is...!!!:O
